Muscle forces become visible in real-time. Forces are invisible by nature, we can normally only see the results of applied forces on the surrounding world. HBM makes it possible to view the generated muscle forces in the human body in real-time, in a way the force transference in the human musculoskeletal system is clearly shown. The real time process shows muscle force and joint torques as real time 3D visualizations of color and form changes in a 3D accurate human body muscle model.
